Question

May i know the best way to solve this question? Tks in advance! 🙏

Answer

Not enough information, breadth of the rectangle is needed. 

unshaded area : total area = 5 : 8

shaded area : total area = 3 : 8 = 30 : 80

A : B : C = 1: 3 : 6 = 3: 9 : 18

So area C : total area = 18 : 80

Area C = 18/80 * Area of rectangle = 9/40 * 34 * breadth of rectangle

It’s kind of a ridiculous question to just provide the length of the rectangle without providing the breadth.  Sigh.
